WESLEY MARVIN HUBBARD, OF CLEVELAND, NEW YORK.

MOLD.

To all whom, it may concern.-

Be it known that I, WESLEY MARVIN HUB- BARD, a citizen of the UnitedStates, residing at Cleveland, in the county of Oswego and State of NewYork, have invented certain new and useful Improvements in Molds, ofwhich the following is a specification.

This invention relates to concrete articlessuch as sarcophagi,burial-vaults, and the likebut the same is not necessarily limited tothis particular use.

The primary object is to provide a novel and comparatively simplestructure that will effectively hold its shape during the moldingoperation and which can be readily collapsed and dismembered in order todisengage it from the molded article without injury thereto.

A further object is to provide means for positively moving certain ofthe parts without shock or jar out of engagement with the article, thuseliminating the danger of checking, cracking, or breaking such article.

Still another and important object is to provide a simple mold whichmaybe employed for manufacturing both the body and cover of the vault orother box without materially altering any of the parts.

An embodiment of the invention that is at present considered preferableis disclosed in the accompanying drawings, wherein Figure l is a topplan view of the mold when'set up. Fig. 2 is a longitudinal sectionalview through the same. Fig. 3 is a crosssectional View. Fig. 4 is a topplan view. showing the core collapsed. Fig. 5 isa sectional view throughthe core, taken substantially on the line 5 5 of Fig. 1. Fig. 6 is aperspective view of one of the corner-pieces. Fig. 7 is a bottom planview of the same. Fig. 8 is a perspective view showing one of the opencorners of the mold with the cornerpiece removed. 9 is a cross-sectionalview showing the relation of parts when a cover is formed. Fig.10 is aperspective view of certain of the filler-bars.

Similar reference-numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated a pallet 11 is employed on which the moldproper is supported. This mold includes outer angularlydisposed side andend walls 12 and 13, the latter being provided in their inner sides withseats 14, receiving the ends of the former. The side walls are providedwith longitudi- Specification of Letters Patent.

nally-projecting stud-bolts 15, that pass through the ends of the endwalls 13 and receive holding-nuts 16. It will thus be apparent that theouter walls can be rigidly, but detachably, secured together, and whenset up and placed upon the pallet they pref erably terminate short ofthe edges thereof. A core is also provided, said core being in the formof a sectional boxing having side walls 17 and end walls 18, each endwall being rigidly secured to one of the side walls and terlinks 21,pivoted at their ends to said sections,

and thus permitting the swinging of the sec tions toward and from eachother. A steady positive movement of the sections toward each other issecured by a connection consisting of draft-bars 22, the outer ends ofwhich are connected, as shown at 28, to the diagonally opposite closedcorners of the coresections, the inner ends of the bars being connectedby a turnbuckle 24, having a threaded engagement 25 with said innerends.

For the purpose of completing the side walls of the core corner-pieces26 are employed, which fill the open corners and constitute, in effect,continuations of the walls, these corner-pieces being carried by angularreinforcing-plates 27, that overlap the walls 17 and 18 and aredetachably secured thereto by screws or other fasteners 28. Bottomplates 29 are carried by the reinforcingplates 27 and have dependingportions 30, that close the ends of the space between the core-sections.This, it is thought, will be clear by reference to Figs. 5, 7, and 8.The remainder of the space between the bottom sections 19 of the core isfilled by a strip comprising sections 31, the opposite edges of whichare beveled to correspond to the beveled edges of the sections 19, theouter ends of the sections 31 being engaged beneath the bottom plates 29of the corner-pieces and their inner ends being disposed beneath a IIOtain the intermediate portions of the stripsect'ions 31 in position.

For the purpose of properly positioning and supporting the core betweenthe outer 5 walls cross-bars 35 are employed which are pivotally anddetachably connected, as shown at 36, to the side walls 17 of the coreand rest upon the upper edges' of the outer side walls 12. Thesecross-bars are preferably disposed directly over the swinging links 21,

and the ivot-aXes of said links are preferably conmcident with the axesof the fasteners 36. The ends of the cross-bars 35 project beyond theouter side walls, and through the same are passed tie-bolts 37, thatalso pass through the pallet 11, thus clamping all the parts securelyagainst relative movement 1 upon said pallet.

In molding the body of a sarcophagus, vault, or box the parts are placedin the positions and relations illustrated in Figs. 1, 2, and 3, anditwill be observed by reference to Figs. 2 and 3 that inasmuch as thecore is of less depth than the outer walls the bottom thereof issupported above the pallet. The material is then poured into the spacebetween the side walls and filling the same and the space between thebottom and pallet will be formed into the article. While plain flat sidewalls are shown in order to avoid confusion, it will be evident that theconfig- I uration thereof may be altered to form pleasing and ornamentaldesigns. After filling the mold the top is smoothed off, and when thewater has run out, so that the inner mold will not float, the cross-bars35 are detached and a V-shaped groove is formed in the top edge of thearticle, as shown in Figs. 2 and 3. The cross-bars are then replaced andthe corner-pieces, as well as the strips 31, are detached, this beingreadily accomplished by removing the fasteners, which will permit thesaid corner-pieces and strips to be taken out. The turnbuckle 24 is thentightened slightly to eliminate the binding engagement between the coreand the article, and thereby avoid hair-cracks in the latter bypermitting the cement to contract without I When the concrete is suffi-:

interference. ciently hardened, the turnbuckle is again operated, whichwill cause the mold-sections to be positively and evenly moved towardeach other because of the swinging link connections 21 and thecross-bars 35, that now i 5 act the same as said links. The core isthereby completely disengaged from the side walls and may be readilylifted out, for it will have sa'asse position between the side walls andrestsdirectly upon the pallet with the bottom uppermost, as illustratedin Fig. 9. said bottom will thus be below the upper edges of the outerwalls, and the spaces between the side walls of the core and the outerside walls are closed by filler-bars 38, that fit snugly between saidwalls and are supported flush with the upper face of the core-bottom bystandards 39, resting upon the pallet. The upper faces of thefiller-bars 38 have longitudinally-disposed grooves 40, that areV-shaped in cross-section. When the parts are arranged as shown in Fig.9, the material is poured upon the bottom until it is flush with theupper edges of the outer walls. Thus a top is formed corresponding insize to the body and having ribs in its under margins which will fit inthe grooves i formed in the upper edge of the body. It

will thus be seen that a simple structure isprovided which willeffectually hold its shape during the molding operation and which can bereadily collapsed and dismembered in order to disengage it from thearticle with out injuring the same. Furthermore, the mold can beemployed for forming both the body and cover of a vault or other box. Itis also to be observed that the parts are simple and are of a naturethat will withstand the pressure and rough usage incident to themanufacture of concrete and similar structures. There is nothing of adelicate or unsubstantial nature that is liable to derangement.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will i be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificingany of the advantages of the invention.
